| 摘 要： | 以实际多机系统为对象，深入研究了可控串补抑制功率振荡的规律。在互联系统中，可控串补应该按照区间主振荡模式控制，当等效惯性中心间转速差为正时容抗值为最大值，转速差为负时容抗值为最小值，这样可以在最小时间内阻尼功率振荡。在长距离输电系统中，抑制功率振荡应该按照主振荡模式控制。

| Abstract: | This paper investigates the rules of thyristor controlled series compensation (TCSC) to damp oscillations in multi-machine systems. In inter-connected network, TCSC must operate in response to inter-area main swing model;its capacitive impedance must be the largest when the rotated speed deviation between equivalent centers of inertia is positive, and be the smallest when negative; so as that the oscillations will be calmed down fastest. In long-distance transmission system, TCSC must operate according to main oscillation model, too. |
